Join Lee Lanier for an in-depth discussion in this video Shot breakdown, part of VFX Techniques: Compositing an Explosion with Fusion 7.
- In this project we're going to be compositing an explosion inside Fusion and that actually takes quite a few pieces even though the shot is only 35 frames long. It's going to require video footage, 3D renders, geometry files and a whole lot of network construction with nodes inside Fusion. Let's take a look at the kind of things we'll be doing. First we'll import the live action footage. This was actually shot as multiple plates, so we'll have to stitch those together.
Next we'll import 3D renders from Maya. These are simulations of an explosion. They're in separate parts, so we'll have to combine them together. We have additional renders of the car, various car parts. We'll combine those with a 2D matte painting in Fusion to make a car that reacts. Can even bring in geometry straight from Maya and render it in Fusion's 3D environment.
We'll pull apart the footage and reassemble the set. We'll even create a 2D stunt double right in Fusion. We have additional renders of fire and debris we'll integrate. We'll combine all these parts and add filters and color grading tools to fine tune the results.
Eventually we'll build up the shot to have quite a bit of detail. We'll wind up after the static version and also we'll create a camera right there in Fusion to create a new bit of motion on the shot. And there we go, the final explosion composited inside Fusion.
